/diy/ - Do It Yourself

And the fan connections

Man, someone needs slapped.

>Blue, black, white, AND green wire.

The green is the ground, don't hook it up to anything. The white is the neutral and the black is the hot wire. Hook the black to the ....the..........one of the wires in the ceiling (normally green is ground and white is neutral). Just hook it up and see if the fan is spinning in the right direction. If not then switch wires.

Or use a tester.

The place was built in the 30's and I was actually expecting worse.

Then one wire is hot and the other wire is neutral. You have a 50/50 chance of getting it right and if you don't get it right the fan spins backwards. No big deal, just switch the wires.

On other more complicated electronics the wrong wiring can destroy them; depending on the electronic device of course.

>>287743
The fan is complicated. What would happen if I connected the previous light only fixture? What would happen if I got the wires backwards on that?

>>287747

Lights don't care much either. Its when you wire complex shit they you can burn stuff up. Fire, of course, could be an issue but I doubt it. Most lamps and stuff don't bother with polarized plugs for the same reason. You can plug it in any way you like and it will work.

Is there a support in place? You know, so the fan doesn't rip the box right out of the ceiling....

Blue and Black to black
Green and White to white

That will do it.

In house wiring, Black and Red are hot, White is neutral. Neutral is the same thing as ground.

Also, this. If the box isn't SECURELY attached, the vibration from the fan can cause it to vibrate loose and fall. Not good.

You want to put a 2x4 between the rafters and lag bolt the box to the 2x4. This will cost you all of 87¢.

fan spins backwards? care to explain that in an AC circuit?

>>287731
Holy shit, I'm looking at that pic, and something is fucked up. That's not 1930's wiring at all, that's some redneck fucked up shit. Do you have a multimeter or voltage sensor? You REALLY need to figure out which wire is hot and which wire is ground. While it's true that it kinda sorta doesn't matter, because of the way the UL protection is made, wiring shit backwards can cause a fire in the unlikely case that the fan were to develop a short.

Might be a good idea to check your panel box and see how they are using the green/white wires. To determine which is neutral. It should be white but then again that green shouldn't be there either.

Then connect which ever isn't the neutral and the black/blue on the fan under a wirenut. Wrap some electrical tape around it so it doesn't slip off somehow. And then the neutrals together. Wirenut/tape.

And just make sure you've got the thing mounted right so it doesn't fall out of the ceiling. Should be fine.

It won't. Dude doesn't have a clue wtf he's talking about and shouldn't be giving advice.

That is a DC motor.

Try to keep up, sweetie.

>>287787
There is NO FUCKING WAY OP's ceiling fan has a DC motor. NONE. Unless he paid like $600 for the fucking thing, it's a goddam AC motor.

Now YOU try to keep up, asshat.

Thanks all. Got it installed just fine. Turns out the white with black stripe was the neutral and green was hot. The box was totally secure and the fan spins fine without any vibration.
